Jack, I dont know if you have any "Half Price Books" stores where you
are. I have found a 1955 and a 1965 ARRL handbooks for $3.00 each.
Might take a bit of looking to find. Also, I see some on Ebay for sale
sometimes. Good Luck. Randy, WB5KCM

And of course, the subject header didn't say it all, since there are various
reasons someone might be looking for a given year's handbook, but not all
of those reasons actually require the specific year.

Lots of times, people have wanted a specific year, and then it turns out
they wanted a certain project from it, and the project was actually in
multiple years of the handbook, or of course had originally been in QST
(maybe even in a fuller form), and that issue of QST may still be available
in paper form from the ARRL (and if not, they may still supply a photocopy
of a specific article for a fee).

The handbooks change like glaciers, so unless someone is trying to get
a complete set or wants the very same edition as they originally bought,
any specific edition is often bracketted by a few years.

But if I got that year, I would get what I want.

What I am actually looking for is the article or project on using 813's
as triode modulators. If that expands the editions, so be it.

JS, Looking at my 1959 Handbook, there's no project using 813's in a
modulator, per se. The high-power modulator in that issue uses 811A's.
The only project using an 813 is an amplifier, utilizing a single
tube. I'll check deeper in that year and see if I missed something
obvious and/or imbedded in the text on modulation/modulators.

I have a 1964 (11th edition) handbook here, and it has only one transmitter
project which is a little QRP 4-tube set, the Knightkit T-60.

The reference was from an ER article in issue 153-155 by W3BYM. His
email in in qrz so I asked him for more info.

However, seems like QRZ email addys are not much good. Most of them bounce.

I will do some searching, but I think the Radio Handbook, rather than the
Radio Amateur's Handbook, may have the article you are looking for. I know
it has an article on using 813s as triode modulators, which is rather
unusual. And, I am thinking it was further back. Will go upstairs to the
radio book library and do some searching.

The 16th edition Radio Handbook (1962) has a "Zero Bias Tetrode Modulator"
featuring a pair of 813s operating as grounded grid, zerio bias modulators
and claims to have 500 watt output. Page 683

I looked in the 11th edition of Radio Handbook and did not find it, but I am
about 87.22% certain that one of the Handbooks features 813s utilized as
triode modulators.

Will keep looking.

Well, could not find it in the upstairs library. Will need to go out to the
hamshack. If it is not there, I will look in the darkroom. Please say
nothing to my wife about my temporary book displacement.
